With our work using the Crysis Sandbox Editor ongoing in preparation for a tutorial we have finally managed to embed the city into the game, as the movie below illustrates.
Working out a smooth work flow has been slightly more problematic than planned with crashes and reboots an added 'feature' to the development. With a bit of patience however it does work. The movie above is work in progress but the engine is coping well with extending the city to almost the horizon.
Below is the city imported into the Oblivion Engine for way of comparison:
See our Oblivion Tutorial for the above, we should be able to get the first Crysis tutorial online next week....
